I had my son's lawn tractor setting in the shop. Just pulled it in there to park it after I serviced it Friday. He had the rear tires loaded with Rim-guard last year. I was in the shop this morning early and then did not go out until after supper. One of the rear valve stems came apart. The metal came out of the rubber. I now have Rim-guard sprayed all over half my shop,tool boxes, and work bench. I had it parked close to the benches so I had room to park the two cylinder tractors that where for sale. I rinsed most of it off with water but it is a sticky mess. I am glad it is not corrosive but it still is a mess. I bet that it will take half a day to clean up the mess. It seems my luck has changed. LOL I knew yesterday could not last.
